“…Our analyses showed that most of the chemical constituents of the all essential oils were sesquiterpenes, which more of 70% in their composition and smaller amounts of monoterpenes, varying between 1.4% and 22.9% (Table 1). Other chemical characterizations of essential oils of P. guajava with the same terpenic nature were found in others works (Satyal et al, 2015;Souza et al, 2017).…”

“…In the superior genotype C7, the most prominent compounds in the oil were α-humulene (20.8%), (E)-caryophyllene (19.8%) and selin-11-en-4α-ol (10.9%). The major compounds identified here (limonene, (E)-caryophyllene, α-humulene, caryophyllene oxide, selin-11-en-4α-ol, and βbisabolol) corresponded to chemical characterizations reported in other studies on essential oils of P. guajava (Khadhri et al, 2014;Soliman et al, 2016;Souza et al, 2017).…”

“…Essential oils extracted from leaves of different P. guajava cultivars grown under the same conditions and in similar environments have shown differential larvicidal activity on the Aedes aegypti L. (Mendes et al, 2017). It has also been shown that the genetic and environmental factor are an important constituent of the composition of the essential oils of guava (Souza et al, 2017). These studies show that the use of these oils can be enhanced by choosing the appropriate genotype.…”

“…The quantity and chemical composition of oils is influenced by several factors that can cause significant changes in the production of specialized metabolites. These can be determined by genetic characters, or by biotic and abiotic factors (Aslam et al, 2017;Souza et al, 2017). The stimuli resulting from the environment where the plant is located can redirect the metabolic route, leading to biosynthesis of different compounds, however genetic variations are very important factors for these variations in the composition of essential oils (Boaro et al, 2019…”

Natural products with biological activity, such as essential oils, can be used in the search for and development of ecological herbicides as an alternative to reduce the damage caused by synthetic herbicides. This work to aimed to determine the chemical composition and phytotoxic properties of the essential oils, at concentrations of 3000, 1500, 750, 375 and 187.5 µg/mL, of four cultivars of Psidium guajava (guava) evaluated on germination and root growth of plant models Lactuca sativa and Sorghum bicolor, as well as in the L. sativa cell cycle. Exposure to essential oils reduced germination and root growth in bioassays, especially at the highest concentration (3000 µg/mL). The essential oils interfered in the normal dynamics of the cell cycle of L. sativa at most concentrations, causing a decrease in the mitotic index and increasing of chromosomal alterations, evidencing aneugenic and clastogenic action. The biological activity of the oils was associated with the presence of sesquiterpenes and monoterpenes found here, such as caryophyllene oxide, (E) -caryophyllene, and limonene. Thus, the essential oils of cultivars of guava demonstrated the promising potential for use as natural herbicides.

“…Indeed, although all these countries are different, they all belong to the Mediterranean region. Moreover, the published data relating to the chemotype of aromatic plants support the influence of genotypes as well as ecotypes (light, precipitation, growing site, and nature of the soil (pH, constituents) seasonal variation), but also the age and part of plant [26][27][28][29] .…”

Chemical composition and antibacterial effect of Smyrnium olusatrum L. Fruit Essential Oil

The plants of the Apiaceae family are mainly used for food purposes and their multiple therapeutic properties and biological activities. This study aims to determine the chemical composition of Essential Oil (EO) of the fruits of Smyrnium olusatrum L. obtained by hydrodistillation in Clevenger-type apparatus. GC/MS analyzed the EO and the antibacterial activity was evaluated against clinical bacterial strains by two complementary methods (Disc diffusion and micro-atmosphere) and determination of Minimal Inhibitory Concentration (MIC). The results of chemical composition show that the EO is dominated by hydrocarbon monoterpenes (55,95%). The antibacterial effect shows that Gram-positive bacteria are the most sensitive to the inhibitory action of EO with inhibition zone diameters (DZI) ranging from 18 to 20 mm for Staphylococcus aureus and Streptococcus faecium strains. The same results were reported with the micro-atmosphere

Myrtaceae is one of the most diverse and abundant botanical families, exhibiting wide diversity in the chemical composition of essential oils (EOs). EOs have various biotechnological applications such as controlling the populations of organisms that negatively impact humans. This study aimed to extract EOs from Myrtaceae species, chemically characterize them, and evaluate their larvicidal and fungicidal effects. EOs were extracted from the leaves of Eugenia brasiliensis, Eugenia uniflora, Psidium cattleyanum, Psidium guajava, and Syzygium cumini by hydrodistillation for 3 h and characterized by chromatographic analysis. Larvaes of Aedes aegypti and colonies of Fusarium oxysporum were subjected to increasing EO concentrations to determine the larvicidal and fungicidal potential. The EOs of Eugenia and Psidium species are primarily composed of sesquiterpenes (>80 %), whereas S. cumini EO is rich in monoterpenes (more than 60 %). The Eugenia species had similar amounts of oxygenated monoterpenes, which may explain their higher larvicidal potential compared to other species, with CL50 of 86.68 and 147.46 PPM, respectively. In addition to these two study species, S. cumini showed a high inhibition of fungal growth, with more than 65 % inhibition. We demonstrated that the actions of five EOs from Myrtaceae with different biological activities are associated with chemical diversity.
